v Specification of Letters Patent.

Patented May 9, 1916.

Application filed October v'2', 1914. Serial No. 865,561.

To all whom it may concern:

Be it known that we,WILL1AMF. HUTSON and JAMES C. BnAsLnY, citizens ofthe United States, residing, respectively, at Barto, Pike county,Mississippi, and'Columbia, Marion. county, Mississippi, have inventedcertain new and useful Improvements in Log-Carts; and we do herebydeclare the following to be. a full, clear, and exact description of theinvention, such as will enableothers skilled in the art to which itappertains to make and use the same.

This invention relates to log carts and has special reference to a logcart designed to raise one end of a pile of logs or. a single log offthe ground so that it may be drawn along by a suitable team of draftanimals.

The principal object of the invention is to improve the generalconstruction of devices of thischaracter.

A second object of the invention is to provide a log-cart. so arrangedthat draft upon the pole of the cart may, if desired, be used to effectthe raisingof the logs.

Anotherobject of the invention is to provide a simple and efficientmeans for simultaneously releasing the shaft of the, hoisting drum andoperatively disconnecting the pole from the hoisting mechanism. 1

With the above and other objects inview the invention consists ingeneral of certain novel details of construction and combination ofparts hereinafter fully, described, illustrated in theaccompanyingdrawings, and specifically claimed.

t Inthe accompanying drawings, like charactors of reference "indicatelike parts inthe several views, and :-Figure l is a side elevationofalogcartembodymg the present invention. Fig. 2 is a top planview ofwhat is shown in Fig. 1'. Fig. 3 is a front view: of

the device' Fig. 4 is a longitudinal section taken on the line 4740fFig. 2. .Fig. 5 is a similar section taken on the line "5-5 of Fig.2.Fig.6 is an enlarged transverse section on the line66 of Fig. 2. y Inthe present embodiment of the invention there is provided a bolster 10which carries the axle 11, said axle serving in turn to support theground'wheels ,12. This bolster 10 has secured to the upper'sidethereofa sand bar 13 and the sand bar and bolster are provided with oppositelydisposed notches 14 wherethrough slides a tongue or pole 15. To the sandbar and bolster are i I connected the hounds 16 and these hounds carryat their forward end a box 17 through which the tongue 15 slides. Inorder to limit the sliding movement of this tongue thereis provided asuitable bolt 18 .30 that when this bolt is inserted in one of the holes19 the movement forward of the tongue is limited. The tongue carries atits forward end the usual clevis 20 and at its .rear end there isprovided a bracket 21 wherethrough passes a bolt 22 having at itsforward end an eye 23 and carrying on its rearward end a nut 24, the eyebeing forward of the bracket and the nut to the rear thereof. Thepurpose of this adjusting bolt and bracket will be hereinafter setforth.

Connectingthe hounds 16 is a cross bar 25 and mounted on the cross bar25 and sand bar13 are the frame sides 26. J ournaled in these framesides is a shaft 27 which forms the driving shaft for the device. Onthis shaft 26 is securely keyed or otherwise fixed a gear 28 which hasformed on one face thereof a clutch member 29. Splined on the shaft 27is a second clutch member 30in the form ofan elongatedsleeve. Thissecond clutch member is provided'with the usual shipper groove 31 and.fitted in this groove 31 is theshipper ring 32. This ring32 is providedwith the trunnion 33 which engages in thesides of a double lever 34.This lever 34 is secured pivotally at its lower end toa bracket 35mounted on the framework of the device and at its upperend this lever34.

ment'is such that by pushing upon the lever the clutch member isdisengaged; Fixed upon the long sleeve 30 formingthesecond clutch member18. a drum. 34 and: around this drum is wound awvire or cable 38 one endof which isattached to the eye 23 whilemovement of the shaft takesplace.

Journaled in a suitable bearing 49 is a" rock shaft 50 which is providedat one end with an operating lever 51. On the other end of this rockshaft is an arm 52 which projects upward in such position as to engagetheend of the arm 36 when the lever is moved in one direction. Thereisalso provided onthis rock shaft a bent arm 53 which is arranged toproject over the side of the frame when the lever 51 is moved in onedirection, said arm 53 engaging with the tail 48 of the pawl so as toraise the latter off of the ratchet. These parts are so proportionedthat the release of the pawl from its ratchet takes place just after thetwo clutch membershave been disengaged by the arm 36 being forcedinward'through the action of the arm 52.

In order to understand the operation of this device let it be supposedthat the parts are in the position shown in the drawing. Now if the stoppin or'bolt 18 be removed and the chains hitched around a log, draftanimals having been attached to the tongue, then if the animals pullforward the-wire causes rotation of the drum 37 If at this time thecontrolling lever 51 is in such position as to permit engagement of theclutch members then rotation of the drum will cause rotation of thehoisting drum through the action of the gearing. When the logs have beenraisedto the proper degree the draft animals are backed up. Now the pawlreversal of movement of "the controlling drum since the clutch membersare so formed asto automatically release when backward When the tonguehas been restored to its proper position the bolt 18 is replaced and theload of logs driven to the place of deposit. Then the operator takes thecontrolling lever and moves'it in such direction as to simultaneouslyunclutch the clutch members and release the hoisting drum shaft.Thereupon the hoisting drum revolves freely and drops the load. WVhenthe load has been dropped the chains of course are unhitched and thecart-is again ready for taking up a second load. There has thus beenprovided asim- Fixed upon the shaft 41 is a gear ple and efficientdevice of the lginddescribed and of the character specified.

It will be obvious that many minor changes may be'made in the form andconstruction of this invention without departing from the materialprinciples thereof. It is not therefore desired to confine the inventionto the exact form herein shown and described,

but it is wished to. include all such as come properly within the scopeclaimed.

Having thus described the invention, what is claimed as new, is f 1. Ina log cart, a frame, wheels supporting said frame, a tongue slidable insaid frame, a hoisting drum, an operative connection between the tongueand drum including a clutch, means to lock saiddrum against unwindingindependently of the movement of the tongue, and means to open theclutch and free said drum from the locking means in succession.

2. In a log cart, a wheel supported frame,

a tongue slidable in said frame, a shaft journaled in said frame andhaving a drum splined thereto, a cable wound around the drum andconnected to the tongue, a clutch member attached to the drum, a gearrevoluble on said shaft and having a clutch member connected thereto tocoi perate with the naled in said frame and having a drum splinedthereto, a cable wound around the drum and connected to the tongue, aclutch member attached tothe drum, a gear revoluble on said shaft andhaving a clutch member connected thereto to coi perate with the firstclutch member, a hoisting drum shaft having gear connection with thegear on the first shaft, a ratchet on the hoisting drum shaft, a pawlengaging said ratchet, aship- 'per lever controlling the clutch, a rockshaft, 'm'eans for rotating'the rock shaft and arms tures, in thepresence of'witnesses.
